One end of the upper fixed beam is connected to the fixed pressing plate, and the other end is connected to the rear column. One end of the lower guide rod is connected to the fixed pressing plate, and the other end is connected to the rear column. A group of lower guide rods are distributed between the fixed pressing plate and the rear column. The heat exchange plates have a plurality of inner holes of the heat exchange plates, and the upper part of the heat exchange plates has upper holes of the heat exchange plates. The lower part of the upper fixed beam has upper guide rods, which are adapted to the upper holes of the heat exchange plates. The upper guide rods are inserted into the upper holes of the heat exchange plates and slide in the upper holes of the heat exchange plates. The lower part of the heat exchange plates has lower holes of the heat exchange plates, and the lower guide rods are adapted to the lower holes of the heat exchange plates. The lower guide rods are inserted into the lower holes of the heat exchange plates and slide in the lower holes of the heat exchange plates. The sides of the heat exchange plates are connected to the rear columns, and a plurality of heat exchange plates are distributed between the fixed pressing plate and the rear column.

[0006] The upper part of the movable pressing plate has a rectangular relief groove, which is adapted to the upper fixed beam. The upper fixed beam is inserted into the rectangular relief groove and slides in the rectangular relief groove. The lower part of the rectangular relief groove has an upper limit hole, which is adapted to the upper guide rod. The upper guide rod is inserted into the upper limit hole and slides in the upper limit hole. The rollers are connected to the upper plate of the movable pressing plate through roller side shafts, and the lower surfaces of the rollers are in contact with the upper fixed beam. The lower part of the movable pressing plate has a lower limit hole, which is adapted to the lower guide rod. The lower guide rod is inserted into the lower limit hole and slides in the lower limit hole.

The side of the strip-shaped push plate has a circular pressing plate, and the side of the circular pressing plate is in contact with the movable pressing plate.

[0008] The side of the fixed push plate has a positioning convex sleeve. The threaded ejector rod passes through the rear column and rotates within the rear column. The threaded ejector rod is adapted to the positioning convex sleeve. The threaded ejector rod is inserted into the positioning convex sleeve and rotates within the positioning convex sleeve.

[0009] 1. For the present utility model, the upper fixed beam and the lower guide rods are respectively connected to the fixed pressing plate and the rear column at both ends. The fixed pressing plate, the upper fixed beam, the lower guide rods, and the rear column form an installation frame. The upper guide rod is inserted into the upper holes of the heat exchange plates, and the lower guide rod is inserted into the lower holes of the heat exchange plates, so that the upper guide rod and the lower guide rod respectively position the upper and lower ends of the heat exchange plates, position the heat exchange plates in the front-rear and vertical directions on the frame, keep the side faces of multiple heat exchange plates aligned, and further align the inner holes of the heat exchange plates. When the plate heat exchanger is in use, it prevents the misalignment of the inner holes of the heat exchange plates on multiple heat exchange plates distributed left and right, which causes inconvenience for water flow in and out. The rear column plays a sealing role between adjacent heat exchange plates and prevents liquid leakage when the plate heat exchanger is in use. The upper fixed beam is inserted into the rectangular relief groove, the upper guide rod is inserted into the upper limit hole, and the lower guide rod is inserted into the lower limit hole. The upper fixed beam and the lower guide rods cooperate to position the movable pressing plate. The movable pressing plate applies pressure to multiple heat exchange plates, reducing the distance between multiple heat exchange plates to achieve a sealed structure. The guide rod passes through the rear column and is connected to the fixed push plate, and the fixed push plate is positioned through the symmetric guide rods to ensure that the fixed push plate is in the middle position.

[0010] 2. The fixed push plate of the present utility model applies force to the four corners of the movable pressing plate through four circular pressing plates, preventing the deformation of the four corners of the movable pressing plate when the plate heat exchanger is in use, making the pressure exerted by the movable pressing plate on the heat exchange plates more evenly distributed. When the plate heat exchanger is in use, it prevents the pressure from being applied only to the central point of the movable pressing plate, causing the pressure exerted by the movable pressing plate on the heat exchange plates to be overly concentrated, resulting in the loosening of the outer sides of multiple heat exchange plates and causing liquid leakage. The threaded ejector rod passes through the rear column and is inserted into the positioning convex sleeve. The rotation of the threaded ejector rod realizes horizontal movement to apply a thrust to the fixed push plate. Furthermore, the fixed push plate applies a balanced thrust to the movable pressing plate through four points, making multiple heat exchange plates closely connected. This device compresses the heat exchange plates through the cooperation of the movable pressing plate, the fixed push plate, and the threaded ejector rod. The horizontal position of the movable pressing plate can be adjusted, and it can position different numbers of heat exchange plates. Description of the drawings
